Problems solved by technology

During the mode switching process, due to the delay in the start-up and shutdown of the chiller, the traditional control strategy cannot guarantee the stability of the water temperature control
Especially for places with strict requirements on temperature and humidity, such as factories and laboratories, it is usually required that the fluctuation range of the water supply temperature does not exceed ±0.5°C. The switching control logic of the ice storage air conditioning system will cause a large fluctuation range of the outlet water temperature, which will affect users. sense of experience

Embodiment 1

[0036] An embodiment of the present invention provides a control method for an ice-storage air-conditioning system, which is applied to a controller of the ice-storage air-conditioning system.

[0037] Ice storage technology is to use low-cost electric ice storage to store cold energy during the low-valley time of the power grid at night. During the peak power consumption during the day, it dissolves water and supplies cooling with the refrigeration unit. During the peak load of the air conditioner during the day, the stored ice is stored A complete set of technologies that can be released in large quantities to meet the peak load needs of air conditioners. see figure 1 A schematic diagram of an ice-storage air-conditioning system is shown, the ice-storage air-conditioning system includes a cold tank (also called a cold storage tank), a dual-working condition host (that is, a chiller unit including two chillers), two chilled water pumps and Two plate heat exchangers and a con...

Abstract

The invention provides a control method and device of an ice storage air conditioning system and electronic equipment. The method is applied to a controller of the ice storage air-conditioning system and comprises the steps that parameters of the ice storage air-conditioning system in a current cold supply mode are adjusted based on the outlet temperature of a plate heat exchanger of the ice storage air-conditioning system; and controlling the ice storage air-conditioning system to execute cold supply operation based on the parameters of the ice storage air-conditioning system. In the mode, the parameters of the cold storage air-conditioning system in the current cold supply mode can be adjusted based on the outlet temperature of the plate heat exchanger, so that the stable outlet water temperature in the ice storage air-conditioning system is ensured, and the experience feeling of a user is improved.

Description

technical field [0001] The invention relates to the technical field of air-conditioning systems, in particular to a control method, device and electronic equipment for an ice-storage air-conditioning system. Background technique [0002] The ice-storage air-conditioning system is to use refrigeration equipment to remove the heat in the cold-storage medium for cold storage when no or little cooling is needed (such as at night), and then use this cold for air-conditioning or industrial cooling peak periods. Through the application of cold storage technology, the running time of refrigeration equipment can be shifted. On the one hand, the cheap electricity at night can be used, and on the other hand, the peak electric load during the day can be reduced, so as to achieve the purpose of shifting power peaks and filling valleys, and saving electricity bills. The difficulty of the ice storage air-conditioning system is to ensure the stability of the water supply temperature during ...
